Uncontrolled Resource Consumption

CVE-2025-25193

Medium
5.5/10

Summary

Netty is an asynchronous, event-driven network application framework. An unsafe reading of the environment file could potentially cause a denial of service in Netty. When loaded on a Windows application, Netty attempts to load a file that does not exist. If an attacker creates such a large file, the Netty application crashes. A similar issue was previously reported as CVE-2024-47535. This issue was fixed, but the fix was incomplete in that null bytes were not counted against the input limit. This issue affects 4.1.115.Final through 4.1.117 Final and 4.2.0RC1 through 4.2.0RC2.

CWE-400 - Uncontrolled resource consumption

An uncontrolled resource allocation attack (also known as resource exhaustion attack) triggers unauthorized overconsumption of the limited resources in an application, such as memory, file system storage, database connection pool entries, and CPU. This may lead to denial of service for valid users and degradation of the application's functionality as well as that of the host operating system.
